Can you advise on:
a) what chemicals are present and leachable from the wood (e.g. arsenic..)
b) what rate of leaching is likely to occur in a humid, temperate,
winter cold region
c) direct us to any documented evidence of bioaccumulation of said
chemicals in domestic vegetable and fruit crops?

Could those of you responding to the above request
send me any information you may have. I have compiled a FAQ on pressure
treated lumber for the folks in the rec.gardens and alternative
healthcare newsgroups. We would greatly appreciate any additional
data on this topic, especially feedback on item c), bio -or- hyper
accumulation in fruits and vegetables.

My FAQ is at sunSITE.unc.edu in the following directory:
pub/academic/environment/pesticide-education/faqs
the file is: pressure-treated-lumber.faq (72kb)

Many thanks.
